CARPET BEATER.

Application filed .Tilly 16,

This invention relates to carpet beaters and is designed as an improvementon the l vork with devices of this character, when constructed in accordance with said patent and as embodied in other forms now on the market, it has been found t-hat the tendency of the beating head is to elongate when the blow is delivered on the rug orcarpet in a well known manner. This is followed by an immediate contraction of said head after the blow and such constant, violent action in the wires or strands comprising the head of the beater soon results in a crystallization of the same with a consequent breakage that renders the beater unfit for use.

The object of the present invention is to so form and strengthen the structure co1nprising the beating head as toetfectually prevent such longitudinal expansion and vide for the necessary resiliency required to dislodge the dirt from theA article being cleaned. Y

Another object is to strengthen the shank or stem of the beater, especially where the same is joined tothe operating handle, and yet retain the necessary flexibility at that point, as well as throughout thev structure, to ailow the device to properly accommodate itself to the inequalities encountered in the surface' of the carpet or rug.

A full and complete understanding of the invention may be obtained from a consideration of the following detailed description, taken in connection with the accompanying drawing forming a part of this specification, it being understood that while the drawin shows a,practical form of the invention, the latter is not to be confined to strict conformity with the showing thereof, but may be changed or modified, so long as suchy changes or modiiications mark no material departure from the salient features of the invention, as specifically pointed out in the appended claim.

ln the drawing, in which similar reference characters parts throughout the several figures Figure 1 is a plan view of the improved carpet beater, a portion of the operating handle being shown.

designate corresponding 1926. Serial No. 122,866.

Figure 2 is a similar detached view showing the formation of one of the strands or lengths of wire used in forming the beater.

Figure 3 is a similar view of the other wire member detached.

Figure fi is an enlarged, longitudinal section through the socket for the operating handle. v

In the construction of the improved carpet beater two separate strands or lengths of suitable wire are used, the same being of equal length and of relatively heavy gage so as to withstand the great strain to which the device is subjected in use. These strands are crossed -at points intermediate of their ends, as indicated at 1, and are twisted or 2 located at the outer or, front end of the beater head and at the longitudinal center .line thereof. 1 Y

That portion of the wires extending from the inner or rear end of the stem portion2 are then extended outwardly atA angles of approximately forty-five. degrees to form angular front struts Sand 4 respectively, while the portions of the wires extending fromthe front end of said stem 2 are bent around to the -left and the right respectively, in a substantially semi-circular shape to intersect the outer ends of the said struts 3 and 4 and form frontcorner loops 5 and 6,

said wires being brought inwardly towards the center of the beater, where they are twisted, as at 7 and 8, with the wires constituting the said front struts, to form what may be'termed side locks.

The wires ofv the front loops' 5 and 6,j

where extending from the twisted vside locks 7 and 8. arethen bent inwardly toward the longitudinal axis of the beater, at an angle of substantially forty-five degrees, to constitute angular rear struts 9 and 10, which in conjunction with the front struts 3 and l provide a very strong and rigid structure allowing a central opening substantially as large as the said corner loops.

Thev remainder of the wire comprising the rear struts 9 and 10` where intersecting each other at the longitudinal center of the beater, are then twisted together for the remaindery of their lengths to provide a rear stem p0rtion 11. spaced from the front stem portion 'wrapped together for a distance to form what may be termed a front stem portion wires .separated or spread apart at an angle as clearly shown in Figure 4l of the drawing.

The remaining portions of the wires constituting the front struts 3 and 1, where eX- tending from the side locks 7 and Se are thenV The w""es constituting the rear corner loops 1li and 15 are then wrapped tightly about the rear portion of the rear stem. 11, for several turns, as indicated at 16 and' 17, the latter coils interlocking with the coils oiv the said stem and the remainder of said wires are then Vformed into circular' coils 19 ot larger diameter, the coils ot one wire al ternating `with vthe coils of the other t-o f form a handle socket 20 into which may be Y screwed a suitable wooden or other handle QL the coils 2O servingl as threads and the ends of the wires 22 tightly hugging the handle so as to avoid injury to the carpet or rug,`and at the same time concealing and 'locking the ends 12 and 13 of stem 11 thereby providing anchorage against elongation.

lt'will be seen, by reference to Figures 2 and 8 ofthe drawing, that the lengths ot wire *comprising the beater, though simultaneously formed during the aforesaid bending j and twisting operations7 constitute closed members A and BQdisposed at opposite angles relative to the longitudinal axis of the beater, and that each includes a front and a rear corner loop diagonally opposite to each other, and joined together by the aforesaid angularly disposed `front and rear, parallel struts, the said iront loops each having one strand of the front stem included therein and the said rear loops each having one strandy of thev handle socket included therein, with the front and rear struts. each having a strand ot the side lock twists ineluded.

The prevention of longitudinal7 sliding movement of the handle socket on the rear stem portion is aided, in addition to the interlocking of the twists 16 and 17 with the twists of the rear stem, .bythe out-turned terminals 12 and 13 which are located at the inner end of the socket and bear against the same.

Any tendency to elongate3 while in use, is prevented in the beater by the provision of the side locks 7 and 8 and by crossing the front and rearv strut wi 1es and continuing the same to formy the rear land front corner loops respectively. v

From the foregoing it will be seen that a simplevand cheaply constructed device hasl been provided of strong and durable construction which will retain its shape under constant usage and prevent `the yusual elongation and other distortion which causes crystallization of the wire comprising the same and the consequent breaking of the same.

lVhat is claimed is A beater composed of a pairof wires twisted together at separate point-s inten Y mediate their ends and arranged to form a series of struts and loops of relatively short lengths, the ends ot the loopsbeing bracedV by the struts arranged :n1 opposite pairs one pair of tree end portionsof the wires constituting the rear pair of loops and beingv twisted together and presenting interlocking coils to providea handle socket,V the other pair o't' free end portions of vthe wires con-y stituting the adjacent struts land being brought together and twisted to constitute a Vflexible rear' stem? the ends of the stem wiresbeing bent outwardly to engage within the coils of the socket and concealed therein,l and the loop wires adjacent to the interlocking coils of the socket ,being wrapped tightly about the stem to prevent a relative longitudinal movement of the latter.

In testimony that I Claim the Vforegoing as my own, I have hereto athxed my signa-ture.
